There are few studies on the differences in clinical outcomes with implant guides made by different methods in cases with a single tooth loss and adjacent tooth supportOBJECTIVE: To compare the use of digital and traditional implant guides in patients whose first molars are absent and who are undergoing implant restoration.
This study included 42 patients with first molars missing who were randomly divided into two groups: the digital group (n= 21) and the control group (n= 21). A CAD/CAM digital implant guide was used in the digital group, whereas a traditional impression was used in the control group. Then, the labor time, the intraoral fit of the implant guide, and the deviation of the screw access channel position were compared between the two groups.
The impression time and implant surgery time in the digital group were less than in the traditional group. The intraoral first fit of the guide in the digital group was higher than in the control group (P< 0.05). The one-time satisfaction rate of the digital group was 100%, while five cases in the control group needed to be redone. In the digital group, there was no significant difference in the deviation of the screw access channel position between implants on the left and right sides. In the control group, the deviation of the screw access channel position on the right side was significantly lower than on the left side. Overall, the deviation of the screw access channel position was significantly lower in the digital group than in the control group.
In a first molar implant, the digital implant guide can effectively reduce the clinical operative time and the screw access deviation and improve efficiency. The clinical results with the digital guide provide a basis for its use in implant therapy for single missing teeth.
关于缺失单个牙齿且有邻牙支撑的情况下，不同方法制作的种植导板在临床结果上的差异，研究较少。目的：比较数字化和传统种植导板在第一磨牙缺失并进行种植修复的患者中的应用。
本研究纳入 42 例第一磨牙缺失患者，随机分为两组：数字化组（n=21）和对照组（n=21）。数字化组采用 CAD/CAM 数字化种植导板，对照组采用传统印模。然后，比较两组之间的劳动时间、种植导板的口内适配性和螺钉通道位置偏差。
数字化组的取印模时间和种植手术时间均短于传统组。数字化组导板的口内初次适配性高于对照组（P<0.05）。数字化组的一次性满意度为 100%，而对照组中有 5 例需要重新制作。在数字化组中，左右两侧种植体的螺钉通道位置偏差无显著差异。在对照组中，右侧螺钉通道位置的偏差明显低于左侧。总体而言，数字化组的螺钉通道位置偏差明显低于对照组。
在第一磨牙种植中，数字化种植导板可有效缩短临床操作时间和螺钉通道偏差，提高效率。数字化导板的临床效果为其在单个缺牙种植治疗中的应用提供了依据。
